An ophthalmic lens having a front major surface and a rear major surface, wherein at least one of the two major surfaces comprises a filter, the filter providing the following characteristics on a major surface comprising the filter: An average blue reflectance index within a wavelength range of 420 nm to 450 nm is 5% or more for an incident angle in the range of 0 DEG to 15 DEG, The spectral reflectance curve for an incident angle in the range of 0 DEG to 15 DEG, Maximum reflectivity at wavelengths below 435 nm, and - a full width at half maximum of 80 nm, (Θ, θ ') = 1- [R θ' ) for an incident angle θ in the range of 0 ° to 15 ° and an incident angle θ 'in the range of 30 ° to 45 °, (435 nm) / R ? (435 nm)], and the parameter? (?,? ') Is 0.6 or more, - R ? (435 nm) is the reflectivity value of the main surface including the filter at a wavelength of 435 nm with respect to the incident angle? - R ? ' (435 nm) is the reflectance value of the main surface including the filter at a wavelength of 435 nm with respect to the incident angle?'. |
